My sharp-eyed friend noticed that, during her appearance on one of Oprah's final shows, Madonna appeared to have been wearing a Cartier gem-set and diamond cross bracelet previously owned by the late Duchess of Windsor. The Duchess is the subject of Madonna's upcoming directorial effort W.E.

The cross bracelet was listed at 350,000 to 450,000 GBP and sold for over 600,000 to an anonymous bidder.
